One hundred ants are dropped on a meter stick. Each ant is traveling ei- ther to the left or the right with constant speed 1 meter per minute. When two ants meet, they bounce off each other and reverse direction. When an ant reaches an end of the stick, it falls off. At some point all the ants will have fallen off. The time at which this happens will depend on the initial configuration of the ants. Questions: (a) over ALL possible initial configurations, what is the longest amount of time that you would need to wait to guarantee that the stick has no more ants? (b) a slightly more technical task: calculate the average time it takes for arbitrary initial number of ants N to fall off the stick.

Phone Screen: -why do you want to work for IXL? -what are some things we can improve on? What did you like? -how would you teach system of equations to an 8th grader? -what do you think an 8th grader would struggle with when learning about a system of equations? -what would an easy problem look like related to a system of equations? -what kind of problem would you write that we don't already have for a system of equations? Written: -given a piecewise function, fix the explanation. -given a third grade Problem on a specific standard, fix the problem and explanation. -pick one of the problems you worked on and list how you would make it more difficult or easier and your rationale. -pick one of the problems and describe how your explanation would change if one of the equations changed.
